Abstract
Combination welding was performed using a CO_2 laser and MIG arc under various conditions to investigate the effectiveness of combining these two welding methods for high speed welding of thick plates. The penetration depth of combination welding at a low welding speed was affected by the assist gas flow rate in a manner similar to laser welding. Penetration was governed by the laser, while the bead width was governed by the arc. Laser-arc combination welding enabled the joining of 12mm thick mild steel at a welding speed of 2000mm/min after proper selection of the assist gas flow rate and root gap.
